Application filed June 17,

To all whomz'zf may concern:

'Be it known that I, ALBERT E. V h-rrrnsmn,

a subject oi I-IisMajesty King'George V of Great Britain, residing in the township ot' Guelph, 1n the county ofWVell-mgton and Province of Ontario, Dominion of C: .i'iacla,.

have invented a new or improved combined Huller, Scariiier, and Cleaner for Clover and Other Such like Seeds, of which the following is a specification. f

It is a well known fact that certain classes of seeds, more particularly those of the clover family andother such like seeds. have not only to be cleaned from'the dust, dirt and hulls, but also have to be scariiiedso that the closely enveloping skin can lie more readily penetrated byinoisture and will at low a better germination. Heretotore the cleaning and scarifying have been done in separate individual and independent inachines of various characters, andthe object .of-my invention is to provide for the efficient hulling, scarifying and cleaning of such seeds in one compactniiachine.

My invention consists ,of 'a' ,new' or in1-.

proved hulling and 'scarii ying' apparatus in combination with screening and winnowing devices and the necessary elevators for passing the unhulled seed through the machine and bagging the same.

I illustrate my invention by the accompanying drawings in Which:

Fig. I is an elevation of my new or improved combined huller, scarilier and cleaner.

. Fig. U: is a sectional elea'ation oi the same.

Fig. III is an end view.

Fig: IV is a detail orsection of the elevating scari tier, and

Fig. V shows the construction oi the scarii ying elevator.

Similar letters of reference indicate lar parts in all the drawings.

A is the frame work carrying my new or improved combined huller, scariiier and cleaner.

B is the circular elevating scarifier, while C is a centrifugal fan for propelling the uncleaned seeds through the elevating scarifier B.

D is the feeding hopper into which tne bulk or uncleaned seeds are poured. They are then fed through the opening eonsimi- 1921. Serial No. 478,395.

trolled lo the d through the 130Ld li diid tle h gred thioii li a s de opening into thecentri'rugal fan 0 "which propels themfthrough the annular c l iambe'r from the hullerand scarifier B. -his annular hullerands cariiicrconsists of a trough shaped peripheryas shown in section F IV closed by means of alone flexible metallic plate lined .yvith .a sa iid-pa per sheet.(b). V,

After the clover has ,beenthreshed .hyan O1'(l11 ary grain thresher, the unhulled seed is runthrough the machine to take oft' the outer hull. This is accomplishedhy means of torcmg the seed against the. rough surface inside the circle of the machine. EUsually cope-icent of theih'ull is removed iirtliefirstoperation depcndingon,thedryness and toughness oi" the hull. The 10,.per centof the seediiot hulled is returnedhy meanso'f thegelevater during the operation.andQagain rm-06d tinst' the rough surface.

driven by the air blast wfrom' the jfan Q impinges against the {sandpaper inner .surff, ace of the outerco'verof the annular huller and scarifier B which, while hulling the seed, also elevates the same and delivers it by means of the nozzle E, Fig. 11, into the chamber F surmounted by a" dust screen and which delivers the mixedbulk or unhulled seeds by means of the chute (f) to the up- 03 its lower extremity into the horizontally inclined trough (h) which discharges the unhulled seed into an outside upwardly inclined elevator L which elevates and discharges the unhulled seeds into the receiving hopper from whence it passes once more through the annular huller and scarilier.

Thiscompletes the hulling and the cleaned seeds now pass once morethrough the first and second screens G, and H. i

As will readily be seen tlie funclleaiied seed The third screen I simply separates the fine dust from the seed and passes the now fully separated seed over the opening in the oscillating screen shoe J- and through the orifice (j) into the ascending air fiume M falling through the bottom of same into the-inclined trough (m) -which carries the hulled seed into the bagging elevator O at the side of the machine which elevates and bags the same ready for further treatment.

Which'the blower is run, the extent of the scarifying. surface over which the seed is forced, the roughness of the surface and the kind and hardness of the legume to be sacrified. For seeds with softer coats than sweet clover'the rate of speed must be reduced and a smooth surface substituted over a portion of the distance. For this purpose a partially worn or smoother strip of sand.

paper is inserted into the machine. l-Vhen the proper speed is used, not more than two per cent of the seeds are broken.

After pasing through the machine a secv 0nd time the now hulled and scarified seed is finally dischargedfrom the machine by the bagging elevator O which delivers the seed int-o bags by means of the usual chute P.

I claim 2- 1. A method of hulling, cleaning and scarifying clover and other seeds, which consists in first scarifying and loosening the hulls; second, removing foreign matter such as straw and debris from the mixed seed and "fine dust; third, rehulling and rescarifying the seed; and fourth, separating chaff and dust from the hulled and scarified seed.

2. An apparatus of the class described comprising a hopper, a flue of channel section associated with said hopper, abrassive means flexibly mounted in said fine, and means for driving material from said hopper through said flue.

3. An apparatus of the class described comprising a cabinet having ahopper and a chamber, a. flue of channel shaped cross section associated with said hopper and Said chamber and provided with scarifying els ments; means for driving material from said hopper through said flue into said chamber to be hulled, other means in said chamber for separating the seed from foreign matter; an elevator adapted to return the'first separated and hulled material from one of said screens to said hopper and said flue for rescarifying, anda fan adapted to carry'off dust from the sacrified material after having passed through the last of the screens in the. series ALBERT E.
